SPECIFICATION forming part of Letters Patent No. 612,211, dated October 11, 1898.V

Application iiled June 12, 1897. Serial No. 640,482. (No model.)

To a/ZZ whom it may concern:

Be it known that I, WILLIAM A. F. MCCAL- LUM, a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a certain new and useful Improvement inI Vacuum Fluid-Elevators, of which the following is a speciiication.

My invention relates to an new and useful 1o improvement in vacuum-elevators, and especially to those used in elevating ales and ,the like, and has for its object to provide a simple and eectve apparatus for bringing about the elevation of the liquid from a barrel or other source into a receptacle or chamber, from which it may be withdrawn as occasion requires.

It is well-known that in the drawing of ale and the like the same must be effected withzo out the liquid passing through the operating parts of the pump, since it is easily contaminated and rendered worthless for drinking purposes, and it is also well known that the old method of creating an atmospheric presz 5 sure upon the liquid within the barrel intensities the atmospheric action thereon and thereby quickly liattens the ale and impairs its quality. From these considerations it has been found necessary to draw such liquids, and especially stock-ale, directly from the barrel through a faucet into the glass or receptacle from which it is to be immediately used, and from the further consideration that such ale is injuriously aifected by being overchilled it has been customary to `place the barrel in the cellar, as conveniently located as possible to the bar from which it is to be sold, and for the attendant to descend to this cellar and draw the ale directly from the bar- 4o rel and return to the bar in delivering the same; but it is obvious that much time is thus lost, and under some circumstances this procedure is next to impossible, and therefore devices have been contrived which contemplate the drawing of the ale directly from the faucet to the glass and then elevating said glass without necessitating the attendant descending to the cellar; but this proved complicated and easily disarranged, whereas my 5o present improvement obviates all of these difficulties and provides an exceedingly simple apparatus for readily bringing about the result without flattening the liquid or impairing its quality in any manner whatsoever. 5 5

In order that those skilled in the art to which this invention appertains may understand how to make and use the same, the construction and operation will now be described in detail, referring to the accompanying draw- 6o ings, forming a part of this specification, in which Figure l is a section of the approved form of my invention, which is intended to be located upon the bar or back bar or other position convenient to the attendant; Fig. 2, a diagrammatical view showing the apparatus in place with the connection therebetween and the barrel in the cellar, as well as its connection to the vacuum-pump.

In carrying out my invention as shown in Figs. l and 2 I provide a suitable stand A, which is preferably hollow, and locate thereon a foot B, which is here shown of circular form, but may be of any other design, said foot having a threaded hub C, adapted to receive the split nut D. Within the hub is seated the flange E of the globe or receptacle F, and the split nut is provided with a flange G, which extends over the flange E in such 8o manner that when the nut is run in place upon the hub the last-named flange is drawn tightly against the foot or a washer I-I, interposed therebetween, and, as is obvious, this will make a hermetically-sealed joint at this 8 5 point between the foot and the globe, it being noted that the globe is otherwise closed, and in practice I prefer that this globe or receptacle shall be of glass or like material, yet it can with equal facility be of any other suit- 9o able material.

As before stated, the nutD is split or made in two sections and secured together by the screws I, the object of which is to aord a convenient means of securing the nut in place around the shank of the globe and above the ilange thereof, and this arrangement facilitates the removal of the globe from the foot when it is necessary to clean the same or for other purposes.

The foot is provided with a shank which extends downward, having a relatively large passage K therein, which communicates with the globe, as clearly shown, and with the IOO section N and a coupling O, said couplingr being secured directly to the faucet P.) A check-valve Q is located in the stand-pipe L for the purpose of preventing the backward flow of the liquid after being drawn upward therethrough, and this valve is preferably so constructed that it mav be uncoupled and removed for cleaning purposes.

A coupling R is connected with the shank J and communicates with the passage K, and to this coupling is attached the faucet S for the withdrawal of the liquid from the globe after it has been elevated there-in, as will be hereinafter set forth.

The plug vT of the faucet S has a straightway-outlet U, which controls the outflow of the liquid, while in the upper portion of this plug is also formed a hole V, :adapted to register with the vent Wand the vent-pipe X, said pipe extending inward and being connected with the shank J, sopas to communicate with the air-passage Y, formed in said shank, and With this passage is also connected the -suction-pipe Z, (here shown-as extending upward within the globe above the liquidlevel.) This arrangement permits the proper quantity of air to iiow inward thro-ugh the pipes X and X to the globe to compensate for the outiiow of the liquid therefrom when the valve-plug is properly turned for this purpose. The pump-pipe c has its upper end also connected with the air-passage Y and, leading downward, is connected with the vacuumpump b, located in yany convenient position, so that when liquid is to be drawn within the globe the operations of this pump will exhaust a certain amount of 'air from the globe above the liquid-level, thereby causing an upward flow of the liquid through the pipe L and passage K.

From this description the operation of my improvement will be, obviously, as follows: Then the attendant desires to draw one or more glasses of liquid fora customer, he simply operates the vacuum -pump while the faucet-plug is closed, as shown in Fig. l, which, as just stated, will exhaust a certain amount of air from the globe and cause the liquid to be elevated from t-he barrel, which should be properly vented to maintain atmospheric pressure therein, after which the turning of the valve-plug-so as to cause the passage U and hole V to properly register with the passage-way in the faucet and vent will permit the outiiowing of the liquid through the faucet to the glass or other receptacle placed therebeneath, said liquid being displaced within the globe by the inflowing of the air, as just set forth. When sufficient liquid has thus been withdrawn from the globe, its outiowing is arrested by the proper manipulation of the .faucet-plug and the balance of said liquid remains in the globe until further needed, vit being noted that the capacity of the globe may be adapted to the particular requirements under which the apparatus is to be operated.

A depression d 'is here .-shown as formed in the globe and may be utilized for the holding of ice or water, whereby a certain amount of heat will be extracted from the contents Vof the globe, and when ice is so placed it may be in cracked form, so as to adapt it for purposes to which such ice is put by the attendant of a bar, and a suitable cover f may be placed upon this-depression, so as to prevent the undue absorption of heat by the cooling lagent therein.

For convenience in securing the stand to the bar or other surface upon which it may be placed a ange g is formed therewith, through which screws may pass for lits sui-t- .able attachment.

Itis also obvious that my improvement may be used for drawing all classes of liquids, and I therefore do not wish to limit it to Aany particular use.

Having thus fully described the invention, what l claim as new and useful isl. The herein-described combination of a suitable receptacle, a pipe connecting said receptacle with the liquid-supply, a checkvalve interposed between said supply and receptacle, a withdrawal-faucet, a suction-pipe communicating with the interior of the receptacle, means for creating a partial vacuum 1n the suction-pipe, a vent also connected to the suction-pipe, the opposite end of which is connected with the faucet, for the purpose described.

2. In a device of the character described a receptacle, a faucet connected therewith, a suction-pipe leading to the interior of the receptacle, a vent-pipe communicating with the .suction-pipe, said faucet having vent andV liquid openings, and a plug having passages adapted to register with the vent and liquid openings, as and for the purpose set forth.

3. The herein-described combination of a suitable, closed receptacle, a pipe connecting said receptacle with the liqnid-supply,acheck valve interposed between said supply and receptacle, a withdrawal-faucet connected with the receptacle, said faucet having a two-passage plug therein, a suction-pipe communicating with the interior of the receptacle, a vacuum-pump connected with said suctionpipe, a vent-pipe also connected with the suction-pipe, the opposite end of which is connected with the faucet, as shown and described.

In testimony whereof I have hereunto affixed my si-gnature in the presence of two subscribing witnesses.
